Resolving Domains Internally And Externally With Bind9 And Caching Nameserver

Filed under
Linux
HowTos

Some times, we are required to resolve our internal domains on a local nameserver and external (internet) domains on our ISP's nameserver. There are different solutions to this problem, but in this howto, we are going to solve it through configuring a combination of caching-nameserver and BIND 9.

BIND 9 is used to resolve domain resolution queries from it own database, as it is SOA (Start Of Authority).

So now it is clear that in our setup the caching-nameserver will be used to resolve domain names externally (internet), while BIND 9 will be used to resolve domain names from our local network (internally).

Now we have caching-nameserver and BIND 9 hammer in our hands, lets start fixing it. Smile

  • Measuring the performance of a community manager
    In an open organization, measuring performance for particular roles like community managers may not be straightforward, especially when comparing those roles to others with more defined success metrics, goals, and outcomes. In my experience over the past six years, I've worked closely with my manager to make sure that we are in sync with my objectives and what I need to do in order to maximize my impact in my role as a community manager.

  • DNSSEC, DANE and the failure of X.509
    As a few people have noticed, I’m a bit of an internet control freak: In an age of central “cloud based” services, I run pretty much my own everything (blog, mail server, DNS, OpenID, web page etc.). That doesn’t make me anti-cloud; I just believe in federation instead of centralisation. In particular, I believe in owning my own content and obeying my own rules rather than those of $BIGCLOUDPROVIDER.
  • 5 reasons wikis rock for documentation
    You may not have noticed, but people often become attached to their favorite technology. This could be a mobile phone, a programming language, or a text editor. When you work on someone else's project, you generally have to go with whatever the prevailing tools and languages are, but when it's your own project, you get to choose the toys. Documentation requires technology, too, but most people have less of a pre-set opinion about documentation tooling than they do about web frameworks and version control systems. So how is a project to choose?
  • Bulgarian government publishes first open datasets
    Bulgaria has just published the first datasets on its open data portal. Currently, about 36 datasets from 26 public agencies have been made available online. The organisations involved were summoned to do so by the Council of Ministers. The Council even has a dedicated team to overcome resistance at the agencies and help them to extract and cleanse the data from the databases. The ambition is to publish another 100 datasets before the end of this year.
